Malleco Viaduct

Malleco Viaduct is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Malleco Viaduct rather than just read about it. In short: The Malleco Viaduct (Spanish: Viaducto del Malleco) is a railway bridge located in central Chile, passing over the Malleco River valley, south of Collipulli in the Araucania Region. It was opened by President José Manuel Balmaceda on October 26, 1890.

Key takeaways

Malleco Viaduct belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Malleco Viaduct to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Malleco Viaduct from memory before moving on to harder problems.

Reference excerpt

The Malleco Viaduct (Spanish: Viaducto del Malleco) is a railway bridge located in central Chile, passing over the Malleco River valley, south of Collipulli in the Araucania Region. It was opened by President José Manuel Balmaceda on October 26, 1890. At that time, it was the highest such bridge in the world. The Panamerican Highway passes right next to the viaduct. A popular myth claims that the bridge was designed by Gustave Eiffel. Eiffel made a bridge proposal, but it was rejected by the Chilean authorities. It was designed by Victorino Aurelio Lastarria and the construction of the bridge was awarded to Schneider et Cie. O Le Creusot, another French company. The bridge was declared a national monument in 1990. The viaduct has often been referred to as a symbol of progress, among others by former President Ricardo Lagos.

Worked examples

Example 1 — a first encounter with Malleco Viaduct

Start with the simplest possible case. Write down what Malleco Viaduct claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Malleco Viaduct before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Malleco Viaduct ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Malleco Viaduct

In research: Malleco Viaduct appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Malleco Viaduct in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Malleco Viaduct is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bridges completed in 1890, Buildings and structures in Araucanía Region, Chile transport stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Malleco Viaduct outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
